programming input precisely set the filter center/corner frequency. Q is also programmed from 0.5 to 64. Separate clock inputs for each filter half operate either an external clock or a crystal. The MAX263 and 267 operate with center frequencies up to 57kHz while the MAX264 and 268 extend the f0 range to 140kHz by employing lower fCLK/f0 ratios. The MAX263/264 is supplied in 28 pin wide DIP and small outline packages while the MAX267/268 is supplied in 24 pin narrow DIP and wide SO packages. All... (read more)

TRIPLE HIGH REFLECTOR HIGH LIDT
In laser applications it is very important to achieve reflection as high as possible over very narrow bandwidth but over wide angular cone. Very high reflection together with proper choice of film and substrate materials, coating design, coating parameters, and substrate cleanliness and surface quality guaranty a very high laser induced damage threshold. This plot shows a spectral performance of a high power laser mirror design that operates @ 266, 633, & 1064 nm @ 45º. 266, 633, 1064nm... (read more)

Ultra-Narrow-Band Tunable Laserline Notch Filter (.pdf)
We report on an angularly tunable laserline notch filter from 760 to 785 nm with optical density of 5.7, 3 dB bandwidth of 9 cm-1 (0.55 nm) and greater than 80% transmission. The notch filter is a single element composed of six bonded slanted reflective holographic gratings in glass.

The ultra- narrow notch filter performance was tested in a single stage monochromator Raman systems to gain access to Raman frequencies very close to the laser line at 488, 532, 633, and 785 nm wavelengths.
All-optical tunable microwave interference suppression filter based on SOA
A narrow passband filter with negative coefficients and a broadband all-pass filter are synthesized to achieve a narrow notch filter with flat passband which can excise interference with minimal impact on the wanted signal over a wide microwave range.

When a is close to one, the resulting very narrow notch filter that must be exactly tuned to the interference in order to get good attenuation.
Considerations in the design of servo amplifiers for high-performance scanning systems
It is inappropriate to try to cancel a lower 0 wide resonance with a very narrow notch filter -the result will look like two very unattenuated resonances side by side.

On one side, thick VPHs can be used as narrow notch filters and their holographic nature allow them to be multiplexed on a unique substrate.
Porous silicon-based notch filters and waveguides
However, this is not a disadvantage if one aims to fabricate a narrow Notch filter , because the width of the stop-band becomes narrower when the index contrast is decreased.
Continuous index IR notch filter for atmospheric CO2 suppression
A 24 cycles digital rugate film was used to achieve a narrow notch filter with bandwidth of ∆λ/λ=6.8%, the transmittance in the blocked area (4.2-4.5µm) was 13%, and 90% in the rest of the 3-5µm region.
